Sleeping sickness

I read on Annabelle R. post that in Africa that there is a disease called Sleeping Sickness. It can be deadly and painful. The disease is from tsetse fly, also known as a parasite called Trypanosoma brucei, that can be found in rural places in Africa. Most of the disease is found in Uganda, Tanzania, Zambia and, Malawi. If bitten you might have red sores, swollen lymph nodes and, really bad headaches. If it isn't treated you can go into a coma then eventually death. If you ever saw or knew someone with this would you tell them about this and help or stay away from them?
